Alter Bridge hit the scene in 2004, and was at the time known to many fans as being essentially a continuation of Creed. Their first album had a ring of the same post-grunge flavor, but starting with their second album “Blackbird,” they’ve set themselves apart as a hard rock band, unblemished by previous ties, despite the fact that three of the band’s four members are now also reunited with Creed. They created a niche based on heavy guitar riffs and dark lyrics, which combined with Myles Kennedy’s outrageous vocal range to make a signature sound. It’s a sound that relies on the dark and dreary aspects of life, a niche they haven’t departed from with their fourth album.
